Amazon is using tech to get even closer to its customers.
It introduced a new sleep tracker, Halo Rise, that learns breathing patterns and senses room conditions to help users optimize sleep. Astro, its home robot, will soon be able to recognize doors, windows, pets and furniture in a user's home.
A new iteration of Blink, its home-security camera, will come with a 360 degree view to capture every corner of a room. And Amazon's Alexa will soon be smart enough — and understand human conversation well enough — to write its own stories when prompted by a customer.
